says: remove R7 for 3.85v output

If you need exactly 3.3v, use a LDO regulator... might need a small amount more headroom than 3.85 so change R7 as needed. I can't remember what the minimum headroom should be but I would use 1V at least.

Yes. Replace one of the LEDs with a diode (1N914 or the like) and you are good to go.
